As the name implies, Nudi Falls is a place for macro-lovers. Nudibranchs are abundant in this dive site, while gorgonians become the perfect spot to find pygmy seahorses.
Scorpionfish, cowries, anemonefish, and giant frogfish can be seen here, along with Banggai cardinalfish. Lembeh Strait is one of the areas where the endemic of the Banggai Islands can survive outside its origin. Night dive is highly recommended to spot striped eel catfish, waspfish, painted frogfish, cuttlefish and octopus, among others.
